3D eCommerce spaces may often be highly populated spaces, with a huge number of users, areas and selling products. Therefore, their design should address different strategies to guide and assist users to locate and to be aware of the most interesting areas, products or users in there. In this paper, we present an approach to enhance and facilitate user buying experience in a large 3D eCommerce space. Specifically, we propose a collaborative recommendation framework which incorporates three types of interactive objects -the User Registration Object (URO), the Interactive Map Object (IMO), and the Recommendation Object (RO)- to guide users along the whole buying experience.
